CL65 Captain reports hot start during attempted cross bleed start. Hot icon and flames and smoke report from aircraft behind cause start to be aborted.

Narrative

The aircraft we were on had a deferred APU. On taxi out while doing our crossbleed start; we received a 'hot' icon on the #1 engine. The start was aborted and the Quick Reference Handbook was complied with. The aircraft in line behind us reported a flame and smoke shot out of the engine during the start. I told the Tower and concerned aircraft we were doing a dry-motor and let me know what they could see from our engine. They said the flame was gone and the smoke was dissipating; but that it was still smoking a little. About that time; Tower moved us to between the runways. I asked again how it looked and the other aircraft said it was still smoking a little. As a precaution; I told the Tower to go on and send the fire trucks out. Once in communication with the fire trucks; we asked them how it looked and if they thought it was OK to return to the gate. They said they did not see any fire danger and that it would be OK to return to the gate. There were no fire or overheat indications; and our Flight Attendant did not have any smoke in the cabin. The hot icon came on at a very low ITT and never got very hot.
