Looking for software/systems to support dialback modem schemes.

[George Hartzell <hartzell @ postgres . Berkeley . EDU>]

I'm collecting information on systems for supporting dialback schemes
for modem access to the "soft chewy center" (smb?, ches?) of a
computing facility.

If you have contact info for any packages/systems, whether commercial,
freeware, or vaporware, please send them my way.  I'd also love
recommendations, horror stories, or "here's how we do it" info.

I'll summarize to the list when the flurry quiets down.
