The ngmoco bert-rpc server (ngbs) uses the 'safe' option to binary_to_term to avoid this problem: https://github.com/ngmoco/ngbs/blob/master/src/ngbs_bert.erl#L21 . Clients get a protocol/data error if they try to do this.

The trade-off is that you then need to ensure that all the modules for your application are loaded before you start accepting Bert requests, as [safe] decoding will stop modules from being automatically loaded.

ngbs has been stable in production use for six months or so, and recently got request evaluation timing support which has been useful for spotting latency problems in the exposed APIs. I'd be happy to answer questions about ngbs off-list too.
