This has been tried before using Javascript - there is no new thinking here. That aside, the problem as I see it, is that the following issues have yet to be solved: 1. You can't currently limit CPU cycles in Javascript reliably 2. You can't automatedly prevent malicious Javascript code from being uploaded and distributed while still allowing people to use the Javascript keywords and constructs that are required for most useful algorithms 3. Any data that is in a format to be processed is not secure because one can view the code and the data, thereby deducing its purpose with minimal difficulty
