Meh, I'd say avoid it.
Multiclass instead into Fist of Zuoken (Psionic Fist in the System Reference Document), which is a psionic prestige class for monks in the Expanded Psionics Handbook. Then take feats like Psionic Fist, Greater Psionic Fist, Unavoidable Strike, Ghost Strike, and Aligned Strike for better unarmed effectiveness. Take the Psionic Meditation feat at some point too probably to regain psionic focus faster and thereby make more frequent use of these psionic feats.
