Hmmm, this is an interesting idea... It would allow setting of the text
from the dialplan as well.  I suppose the main question is whether the
variables are indeed specific to that channel, or if they are global? I
don't want them 'stepping' on each other...

It sounds like what I want to do is simply use the same manager
interface like this:
Action: Setvar
Channel: Zap/1-1
Variable: mytext
Value: blahblah

This would be the same as:
Setvar(mytext=blahblah)
when channel zap/1-1 was still running through the dialplan.

Comments/suggestions are welcome.

I'll look into this further and let you know what I work out.
