:) Yes, it is a unfortunate postion at the moment. There is Kom, Swazoo and Hyper. Kom is really basic (and not existent in gemstone, but pharo). Swazoo and Hyper are more into "the real thing". But even swazoo and Hyper seriously lack support for most of the stuff. They support GET and also POST in a urlencoded fashion. That is everything seaside needs. If your needs are beyond that you're out of luck. To repeat my rant I would call it that they are overengineered for what they support working. There was good thinking in both of them as far as I can see but probably they are just unfinished. Zinc is different because it has full support for most things you really need. Zinc should be working in gemstone but I wasn't lucky to get it running reliably. Some more effort needs to be done. 
If you want to do POST then you should think if you can live with urlencoded data. That should work in any of the mentioned adaptors. Of course you want to just use the body but that's a no-go as far as I can tell.
I don't like the situation and I don't like my free time only leaves enough space to complain (instead of just fixing it) but anyhow we need to get zinc running on gemstone. In pharo the situation is just wonderful and I did newer projects in pharo instead of gemstone because of that (and SSL).

Sorry, for not being of any help here,
