The technology would be implemented into "Microsoft’s more portable hardware and software services, including Windows Live, the Windows Mobile OS for smartphones, and the Zune media player."
Musiwave co-created an online service called MusicStation, "which lets cellphone users pay a weekly subscription fee in exchange for unlimited song downloads, similar to the monthly Zune Pass subscription."
This could be a good acquisition for Microsoft, especially if it does indeed extend the technology to Zune devices AND to Windows Mobile devices. The Zune could use such a feature to help it compete with the iPod Touch. If it had an all-you-can eat subscription option versus the Touch’s $1-per-song downloads, it might be able to gain some ground. And Windows Mobile, come on. We’ve been waiting for a direct-download subscription music service forever here.
