The PIC family is very similar to AVRs.  The picPET and friends are 8 pin 
DIPs so the Wife is unlikely to notice the additional clutter.

Than you want a second serial port for things like this.

Or maybe you can use the parallel port if your system is old enough to have 
one.  I haven't tried it, but I think Linux has a module that supports it.
