474V remotes, also 519H home kit

Just wondering, is there is a list of older alarms and remote starts that will program with the new viper 474V.  This is a question that we have come up in the shop all the time….”I have an old sidewinder alarm and I need a new remote”…..same thing with other alarms like avital and hornet.  Also has anyone used the home automation garage door interface module, 519H, I was wondering if the Clifford 3.5 could be programmed to it using one of the 200ma negative trigger output channels….that would be sweet
