Re: [orca-list] Pluginsystem for Orca using libpeas

[Linux A11y <chrys linux-a11y org>]

Howdy Andy,

Yea, thats the way i designed it currently. The plugins can access to an API exposed by orca.

If you know some interesting internals her, maybe we can cherry-pick the good parts of NVDAs concept.

I usually hang around in IRC:
irc.linux-a11y.org
#a11y

Maybe a more direct talk would be an good idea to do that?
