I would do it that way:

I would use hints file to rewrite the User-Name depending on the
Called-Station-ID and Medium-Type.

This way you could:

- rewrite dialup user bob into bob at isp1 when Called-Station-Id is present
- rewrite DSL user bob into at isp2 when Called-Station-Id isn't present

This way you can have bob at isp1 and bob at isp2 into the same database
without any problem.

It's a bit tricky, any easier way Alan ?
