extract psql meta-commands into library?

I'd like to provide access to psql's "backslash" meta-commands for
IPython's %sql magic, as well as some other non-psql tools.  When I
asked about standalone implementations of the meta-commands, Craig
Ringer suggested that extracting them from psql into a libpsql library
(which psql would then use) would make that easy for all matter of
external uses.

Does this sound doable / of interest?

ipython-sql: https://pypi.python.org/pypi/ipython-sql/0.3.1

Thanks!
