Hi,

I've read on your wiki the SFLvault section. Actually, SFLvault-server uses SQLAlchemy, so can use MSSQL/MySQL/PostgreSQL/Oracle/SQLite, etc... It's just easier to deploy with SQLite :) Other things to note, is that it is scriptable in Python... we also recently updated the Debian packages, and Simon Piette packaged an .rpm for Fedora (for the client). The server is better installed in a python virtualenv, so the versions don't conflict with system-wide python libs.

We've also ported the server to Pyramid (it was initially Pylons), wrote a bunch of tests, and wrote some documentation to be published on Readthedocs.org.

Any help is welcome :)

Micropayments is exactly what giftfile is made for, and see by yourself (http://www.giftfile.org/ it seems very promising.
