[sr-dev] mtree module mt_match() api function

LCR module load_gws() call can currently filter matching gateways based on regular expression match of From URI. I was thinking to add as an alternative to the regular expression match a match based on mt_match() of mtree module. That would require that mtree module provides an API function corresponding to mt_match() script function. Does such an API function sound like a feasible thing to implement or does there already exist better ways to achieve the same? -- Juha
