TDB is not "plain text" it's a key/value store, like BDB/etc.

My guess is that sqlite would be nicer though, as I'd imagine you
wouldn't want to store just key/values.

I can't think why you'd want a plugin, but you'd probably need to use
the yum API ... at least so you could get data out of yumdb. The
"client" side should be truly trivial though. Dumping the installed
packages, which repos. they came from and the reason for their
install ... is probably like 10 lines of yum code.
If someone is doing this work, they'd probably do a bit more to get
more info. ... but again, it would be trivial in comparison to the work
needed on the server side (and to get people to install it etc.)
