Perhaps the best two browser techs for this are Canvas  with Flash as a back up   We tried VML on IE as backup for Canvas  but it was much slower than Flash  SVG was slower then all the rest   With jSignature   http   willowsystems github com jSignature    we used Canvas as primary  with fallback to Flash-based Canvas emulator  FlashCanvas  for IE8 and less  Id  say worked very well for us
