Other profiles could be defined that describe how to work with certain data files (such as a MIME file) without any specific protocol. This will allow to create such a separate filter box that you mentioned but have it negotiate with different proxies and gateways what kind of protocol/data it can handle. Today a protocol such as ICAP is hacked and misued to work with other protocols than HTTP.
