[plt-scheme] What's the latest on the Scsh port?

I googled for a porting project, but it seems the last time scsh and plt
were mentioned together was over a year ago.

Is Paul Steckler, or anybody, still working on this?

I was first looking for a POSIX module (for low-level IO calls, signal
support, tty stuff) - which, apparently, doesn't exist -  and that led
me to scsh.

I'm interested in working on one or the other, but I'm rather new to
plt, so would do better under another's aegis.

Cheers,
