Each interface can have 65536 peers. Each linux system can have
multiple interfaces.

(If that peer limit becomes a problem for somebody, it wouldn't be
difficult to remove it and expand it to 4294967296.)

You can load the keys into the interface using wg(8). At some later
date there may be support for dynamic database stuff.
