I'm pretty sure that help with cryptsetup integration into the Debian
Installer (D-I) is highly appreciated by the current D-I developers.

As a starting point, you might want to check the following resources:

request for support to integrate existing encrypted devices in D-I:
	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=451535

slighly outdated wiki page about cryptsetup integration to D-I:
	http://wiki.debian.org/DebianInstaller/PartmanCrypto

git repository with partman-crypto code:
	http://anonscm.debian.org/gitweb/?p=d-i/partman-crypto.git

Greetings,
 jonas
