Large SOAP Attachments

One problem of webservices is sending large data chunks around - something you want to minimise. SOAP attachments are not ideal. One way to avoid sending data through SOAP is through the use of a URI (LSID) referral - which will delay fetching data until the last moment and may be optimised, e.g. through a bittorrent download (as discussed on Bio.share/Bio.slurp).
