Is there a limit to number of paired bluetooth devices?

MacBook Pro 13 uni. Paired devices: Apple Bluetooth Keyboard, Magic Trackpad, headphone/mic, iPhone 4. My keyboard is randomly going in and out of connected/disconnected. It's not battery related. The music in the headphones is not choppy, so that doesn't seem to indicate saturation of bluetooth bandwidth.

Somebody can correct me if I am wrong, but a 'computer' (in the traditional-sense, with a 'full' OS of sorts) should be able to pair with infinite devices. Now that doesn't mean you'd be able to use them (reliably, anyway) all at the same time - say if you had 50 devices paired.

On the other hand, the Bluetooth device is limited to how many computers it can pair to by the hardware, and usually that depends on the type of device it is, as well (two+ being common these days).

From Wikipedia:

A master Bluetooth device can communicate with a maximum of seven devices in a piconet (an ad-hoc computer network using Bluetooth technology), though not all devices support this limit. The devices can switch roles, by agreement, and the slave can become the master (for example, a headset initiating a connection to a phone will necessarily begin as master, as initiator of the connection; but may subsequently prefer to be slave).

The Bluetooth Core Specification provides for the connection of two or more piconets to form a scatternet, in which certain devices simultaneously play the master role in one piconet and the slave role in another.

At any given time, data can be transferred between the master and one other device (except for the little-used broadcast mode). The master chooses which slave device to address; typically, it switches rapidly from one device to another in a round-robin fashion. Since it is the master that chooses which slave to address, whereas a slave is (in theory) supposed to listen in each receive slot, being a master is a lighter burden than being a slave. Being a master of seven slaves is possible; being a slave of more than one master is difficult. The specification is vague as to required behaviour in scatternets.

Getting more than five to work reliably can be a real pain.

Is there a chance it accidentally paired to a mac in another room? PITA I've had to deal with repeatedly.
