I simply never heard of. Cyalume (CYLUW.OB) is another company with such a unique product that there really is no viable alternative, but that is due to rare and unusual circumstances (market size has traditionally been too small for large companies to undertake the necessary R&D, and CYLU has literally 100% of the government contracts for their core products, making it impossible for a smaller company to catch up R&D-wise without substantial financial backing).
