i signed up for an account to use with my gmail account and installed the software on my apache/6700 (it's about 2 megabytes). i already had my work exchange account being pushed to my device and windows live installed to push my hotmail too. so, the software allowed me to add a third push account. it even allows for additional email accounts to push - i just dont have any more to add. the software integrates well and creates another mailbox which is accessible same way as others. even better there does not seem to be any additional battery drain like windows live mobile seems to cause when set to 'sync as mail arrives' i didn't have any problems at all after a soft reset.
here's a thread from pocketnow.com where a guy has it working well on his dash:
