I agree with Yucca guatemalensis http://davesgarden.com/guides/pf/go/734/
olddude - I believe it - the tips are sharp. What I've had "near misses" with are Phormiums and trying to pick them up in containers and almost taking out an eye. Either that or bamboo stakes in vines and bending down to pick them up.
I still cannot come to a conclusion here. Thank you for your comments. The next time I am near the plant, I will take a few more detailed pics to post so we can get a better idea of how the leaves are configured and maybe a close-up of the bark (stem). I just don't think the leaves are firm or sharp enough to be a yucca.
If given the proper growing conditions it would most certainly show as an unmistakeable Yucca. This truly is not considered in my mind to be a house plant, unless optimum conditions are available…Strong Sunlight, excellent drainage, etc.
