SRP is being implemented into SSLSRP is being implemented into SSL, so browsers are beginning to support it. Another option (albeit, much slower) is to run SRP in Javascript. Since the server supplies the javascript code, however, this is an attack point. So, it would have to be delivered over SSL, and the client must trust the server, which makes SRP with Javascript less than ideal.
There is more information on using SRP with OpenSSL, which seems fairly current.
