I think if anything, you better overload "#" than "?".
The part after "?" is sent to the server, the part after "#" is
not. In your case, it's the browser that has to disentangle
the additional information and load the various frames.

An additional advantage is that the syntaxt after "#" is not
very abused yet, so that it is easier to introduce new conventions.
