I imagine it would be possible, although i'm not in charge of that. :)

I'm sure this would be fairly easy to control, especially if QCA is imported

We like incremental development around here. :) I would definately go with the
adding pieces approach. just my 2 cents.

My "idea" for the import of QCA would be something along the lines of this:
We import it into kdesupport. This will make it easier to keep the things from
happening to it that we don't want to happen to it, namely keeping it
cross-platform compatible. It will also allow you to do seperate releases,
etc. since the kdesupport module doesn't follow the normal kde release
Maybe some API documentation will get added. Brad seems to be a master at

In short, I and a few other people who i won't completely vouch for, want to
see this library be used by kde, and if we can give it a permanent home, even
better. QCA will also allow us to do a bunch of other things with our crypto
layer that we couldn't do before, and i'm quite excited about getting it
imported into kde cvs (finally).
