  Which reminds me, what directory do I rebuild the source from for GPC?

   You have to think about the loud majority that don't have VBE2 tho. Not everybody has the UniVBE driver, think of how upset the person would be if they bought your game or application only to find out that they have to pay more (especially when they
consider that they've spent enough as it is). Another thing is that VBE2 hasn't caught on to Video Card BIOS's yet, not everybody has a Matrox Millenium II. My point is that you can support it as an enhancement, but your libs should not depend on the
driver being VBE2. Disregard this if you support direct bank switching for VBE 1.2+

  One of my major goals is simplicity. I aim for the beginner (hence the API being as it is), the novice, and the advanced user (exposing the virtual screen buffer for custom operations).

   If you go with the COM architecture, I'd suggest writing a wrapper API to target the users who want to focus on the algorithms rather than the coding, or for the beginners.

  Somethign else you should consider is how you plan to release the code, I noticed you have it under the GPL, it may be better to release it under the LGPL, it gives the user more flexibility on how they can use it, and also retains your copyright.

See ya!
