To save some time/ guess work regarding package info, did you manage to get dpkg -l (small L) output? I'm by no means an expert on any of this. Depending on apt cached db you might be able to get a list of available packages from the unknown repo.

I don't see much use in the other apps, given their age as a security product. The rdesktop-m5ui could have use if rdesktop is still actively maintained for Leste. The other VPN related bits, we would probably still be better off building up to date openvpn. I seem to recall someone even suggested it as a built in icd2 plugin.
