[SR-Users] Xcap server chooice among openSER, mobicents and openXCAP

hi guys, it is my first time to use XCAP, i want to implement XCAP server to support maybe huge amount of user accesses (as cloud solution), so far, i can find out three XCAP server solution: 1. openSER with XCAP Server Module http://kamailio.org/docs/modules/devel/modules_k/xcap_server.html 2. mobicents with XCAP component/server build-in http://code.google.com/p/mobicents/wiki/Welcome?tm=6 http://www.mobicents.org/diameter/index.html http://hudson.jboss.org/hudson/view/Mobicents/job/Mobicents-Books/lastSucce… 3. openXCAP http://www.ag-projects.com/projects-products-96/101-openxcap but i am not clear to choose with solution to best match my situation (high volumn, high scale, and quick response). - does openSER support the cloud solution with high volum, high scale? - is it easy to use/integrate the XCAP server independently from mobicents? - is there performance issue for openXCAP, because it is implemented using python? any suggestions would be appreciated! best regards, -iamsy
