Meebo adds file transfer to Web IM
Meebo has just rolled out an update that includes a few new emoticons, and oh yeah, support for transferring files. Don't expect to send huge videos over the service though. There's a 10MB size limit on files you transfer, and a 30MB per user limit per month.
Meebo is using Amazon's S3 storage service and EC2 scaling service to facilitate file transfers. So don't expect those file size limits to go away anytime soon. But this is definitely a step in the direction of making Meebo a complete replacement for desktop-based instant messaging clients.
