As would I. However, due to the computer resources it takes per question it would be extremely expensive to scale.
Watson is made up of a cluster of ninety IBM Power 750 servers (plus additional I/O, network and cluster controller nodes in 10 racks) with a total of 2880 POWER7 processor cores and 16 Terabytes of RAM. Each Power 750 server uses a 3.5 GHz POWER7 eight core processor, with four threads per core. and it still takes ~15 seconds a question.
PS: Rough order of magnitude: 90 IBM Power 750 ~= 180 EC2 High-Memory Quadruple Extra Large Instance * 15 seconds ~= $1.50 a question. (Edit: that's probably still low, each of those 750's have 16TB / 90 = 180GB of ram).

Edit2: Ouch 90 times 32 core IBM Power 750 list price is 492,210$ a month or 2.84$ per 15 seconds (http://www-03.ibm.com/systems/power/hardware/750/browse_aix....) and those only have 128GB of ram,
