wimba vulnerabilities?

[Gary Dobbins <dobbins () ND EDU>]

Has anyone done a study of the Wimba Voice service (www.wimba.com), toward verifying its degree of risk 
(vulnerabilities exposed, etc)?  Our campus is considering using it to store voice clips as part of the curriculum 
support system.  We're having a hard time getting complete info about the technology behind its attack surface, so 
would be grateful to hear from anyone who has experience with this product.

Thanks.
