Can I have a dimmer on each of the 2 switches? On sw1 I have a hot and
2 travlers, sw2 has the 2 travelers and the load(light fixture). I can
only get a dimmer to work at sw1. Do I need a second hot wire a sw2?
Well, at sw2, you could put in a regular 3-way switch, and a dimmer
next to it connected to the single wire, and that would *further* dim
the lignt, I think, but I don't think you could get it to full
brightness if you have the dimmer turned down at the other end.
Wait a second. Maybe that's what you mean about the second hot. If
you ran a hot from sw1 to sw2=location but connected it to a dimmer,
you could get the brightness up to full level, but then how would you
turn it down at the sw-1 location.
This needs someone more clever than I am.
Whatever you try, I'd set it up on a table first, and plug the whole
thing into a wall outlet, before I bothered installing it. The heavy
version of wires with alligator clips on each end are quite useful for
things like this.

I believe there is an X-10 system that will handle that need. That way
you use one master and the others control the master through the existing
wiring, no need for any travelers.
In the X10 system, one of the devices (called "master") replaces one
of the switches. It is wired as a single switch (using one of the
traveler wires). The module has an additional (red) wire which is
connected using the other traveler to a button at the other end.

For a standard 3-way switch setup I think you can only have one of the
two switches be a dimmer. I cannot recall if this is an NEC thing or
limitation of the hardware. Might have something to do with the fact
that dimmer switches tend to get kind of hot. I recently installed a
dimmer on a three way and l limited the wattage to 390w on a 600w
dimmer. I think NEC allows up to 80% wattage on the dimmer rating and
I'm at 65%. hooray for me
