BlueService for Mac

From DEVONtechnologies:

This service sends selected plain or rich text of Cocoa applications (e.g. Textedit, Mail, Stickies, Notes, ProjectBuilder, Fire, OmniWeb or TeXShop) and of Carbon applications supporting services to BlueTooth devices supporting OBEX Object Push or OBEX File Transfer. Therefore it's possible to send notes or short messages to your handheld or your mobile phone (especially useful if your phone isn't supported by Jaguar's Addressbook and its SMS capabilities).

Note: If you can't send small plain text files to your Bluetooth device using "Bluetooth File Exchangem" then BlueService probably doesn't work either.
