Under "Lightstreamer\DOCS-SDKs" within the Lightstreamer software distribution, you can find the "Network Protocol Tutorial.pdf" document, which explains a network protocol (based on HTTP) that can be used to implement a Lightstreamer Client with any technology. You just need to access client sockets or, better, an HTTP client implementation.

Starting from Server build 1362, that documentation will be available under "Lightstreamer\DOCS-SDKs\sdk_client_generic".

Please let the community know if you try to develop any client using this network protocol.
