This would be a nice feature, less overhead for the donator too as the amount donated can automatically be split up among all of your starred projects. Bonus points to offset a sponsor dashboard where you can use a slider to change the percentage splits. In the future a budget feature can be added for sponsored projects and this dashboard can show which projects haven't yet met their budget for the month or quarter, similar to the banners that show on wikipedia, "this is an open source project and need x amount in order to keep operations going smoothly, if everyone donates y amount that will fund development for z time period."
