the best explain is:
owfs is very good (file acess to digital/analog values, http access, tcp/ip,
ftp, etc etc)
should be nice having it with spi/i2c
the problem: onewire is slower than others protocols (spi, i2c, modbus, etc
etc)

What happens now with your Lotus Notes apps - do you make another costly
upgrade, or settle for being marooned without product support? Time to move
off Lotus Notes and onto the cloud with Force.com, apps are easier to build,
use, and manage than apps on traditional platforms. Sign up for the Lotus
Notes Migration Kit to learn more. http://p.sf.net/sfu/salesforce-d2d
