Premise: if you want to get help on a given deadline you should get those support contract with various support levels that guarantee a response within N hours. This mailing list is providing help on a volunteer basis, so people help when they feel to and have time, "I want help fast" "This is urgent" or the many variants of this message are annoying. That said, nothing in the Feature hierarchy implements Serializable, if you make a Serializable collection you'll find that feature themselves are not serializable. Use a format that is meant for the network, such as GML or GeoJSON, to send over a feature collection. I'd suggest you have a look at the gt-geojson module, it's still not supported but should give you decent performance without tying the two ends talking to be written using the same version of Geotools or, for what is worth, both being written in Java.
