Can anyone tell me what I need to do to publish selected content from my SharePoint intranet to the internet? Are there licensing concerns?

If you mean that you want to extend an Intranet Only MOSS 2007 installation and make it an Intranet + Internet MOSS 2007 installation, then, Yes, there are licensing concerns. 1. Server-based INet connector ca 2K (per server connected to the Inet) 2. MOSS 2007 INet connector ca 30K (per MOSS server connected to the Inet). If you meant something else, please say more exactly what.

I think you have answered the question. Just to clarify, even if i only want select portions of intranet sites to be visible to the internet I will need additional licenses?

Yes, it's the fact that your MOSS system is open to the Internet that causes the license requirements not how much of it is open to the Internet. (In the same way that if you buy MOSS you pay the same price (for each of the two versions) for the product and CALs even if you don't use all the functions included in it) By the way I can never remember the exact names of those two "Internet access" licenses but the split is correct as is the necessity for it. But as with all licensing issues, use the above as a basis and then contact a Microsoft licensing specialist to get the exact details and prices confirmed.

Excellent, are there any technical challenges, once the licenses are paid for?

Yes :) You should search for a Microsoft paper on Extranet (i.e. I know that at least one detailed article exists). If you don't find it via Google/Bing try searching the MS Articles list of my WSSv3FAQ site (see sig) which has (+) has only SharePoint articles but (-) only indexes the titles of the articles not the content.

Do these additional extranet licenses need to be purchased even if I have an enterprise license?

About Clients with WSS v3 intranet used as extranet? Sure there is no licensing issues involved

Yes. Whether or not you have the Standard or Enterprise version is irrelevant when asking about Extranet - that's only relevant for users of CAL licensing because then they would need both Std and Ent CALs (Std only for a Std installation). Sorry for the delay. I've been on holiday for a week.

Just to add to Mike's excellent answers, the licensing is based on who the audience for the content is, not what actual content is published. So making only select portions of your sites available has no bearing on licensing. What does make a difference is who is viewing the content. When you say "internet" that typically means that you want to make the content publically available, i.e. any random member of the puclic can enter your URL, or find your site on google and view some content. For this you need the expensive internet connector licenses. Another scenario would be an 'extranet', whereby only your current internal users would be able to view the content, just they can now access it remotely as well. The site is available over the internet, but only your existing internal users can authenticate to it and view content. As far as I'm aware this doesn't need any additional licensing. There's other scenarios in between, such as making the site available to select users from another organisation and so on. It's probably worth talking to the licensing partner that you bought your current licenses from and discussing you scenario in detail with them
