What complexity do you want to add into scheduled transactions?

As Derek mentioned, this may not be as easy as you hope...  Currently,
non of the SX functionality is exposed to guile, and there's no
already-defined or clear-cut 'hook' locations.

Guile and C interact in gnucash in two primary ways:

* guile-native functionality made available to the C code -- e.g., 
  reports [somewhat]

* C code wrapped for guile -- e.g., the Engine, GUI interface 

Look for the '.spec' files to see the declarations for the later, which
is provided via g-wrap.

Those declarations are pretty straightforward, so if there's
functionality you want in guile that's not already available, it should
be easy enough to wrap it.

At the same time, I believe we're more interested in ultimately
_reducing_ the volume of scheme code in gnucash, and moving to SWIG for
bindings to other languages...

The code is the best documentation, at the moment.
