THANX for the suggestions gits. I'm sorry I can't be more open minded about this to be able to consider them, but there are pretty unique aspects to this job that require a browser front end and standalone capability, plus code protection that's more robust than depending on people to honor copyrights.
I'm developing the system on my web server - it's nearly complete and you can
see it there, but you won't see very much because it's all login controlled. This system will import and export member data from a state database, but its database can be downloaded to a laptop where an IIS served version of the system resides, so that it can be deployed for use at locations where there is no internet connectivity.
As to speed, that's not an issue, although the decryption required for page delivery will be compensated (maybe even providing faster response time in the end) by the smaller encrypted file sizes (all comments and white space is removed from the asp pages in the encrypting process). As we all know, there is no such thing as unbreakable encryption, but according to HTMLGuardian's claims, it would take much longer to break their encryption than would be worthwhile for someone inclined to attempt it.
My main reason for posting this question was to see if anyone knows of other products than HTMLGuardian that might be better - either cheaper, easier, or more robust.
