I posted some house rules sometime back which I won't repeat here, and also discussed this idea with Jason Hardy at Gencon last year (Which he really liked). Basically the idea is the a technomancer can use Resonance with all technology, not just the matrix. Since TMs use basically the same rules as Magicians, they can be given a list of Adept like "Powers" they can buy that mimic cyberware/bioware. Just like an Adept/Magician can get around the restrictions of cyberware/bioware, for example, by using the Improved Reflexes Power or Spell, a TM should have some mechanic to also get around their rescrictions on the use cyberware/bioware as well. In fact, since Resonance works on technology it makes much more sense for them to be able to do this. I would just convert all Echos to these Resonance Powers (and add a bunch more) and then give the TM a "Power Point" when they get a new level of Submersion. And give them a number of these Resonance Power Points = Resonance at character creation just like an Adept. I would keep these "Resonance Powers" to be limited only to things technological. If it can be done with Cyberware/Bioware then the TM should have powers to emulate these. This would also allow a player to not only have a "Resonance Decker" at character creation, but they could also create a Resonance Rigger or Resonance Street Samurai archetype as well. It would open up the TM to so many new options. TM is a very cool concept and I think something like this would take them to the next step and make them very flexible and very fun to play. Just my 2 cents.
